As an important component of e-business interaction, mobile payments, such as e-cards, have been widely used by the public due to its advantage of face-to-face interaction.

Currently, data interaction solutions for e-cards are mainly based on one online account and one payment account (an offline wallet or public transport card), wherein the online account is used for online payment so as to recharge the payment account. The recharge solution thereof is that a user is provided, at a fee, with a mini card reader valued at around 100 Yuan and the recharge is completed by means of the card reading chip embedded in the mini card reader. Correspondingly, the interaction solution thereof is that data interaction is performed by means of the card reading chip embedded in the mini card reader.

Since the loss of a public transport card as the payment account cannot be reported, however, people generally are unwilling to recharge a relatively large amount to the card, which leads to the need of frequent recharging for the payment account, while the mini card reader is not convenient to carry around and recharging queues are criticized by the public.

As is apparent, the embodiments described below are only a part of embodiments of the present invention, rather than all embodiments thereof. All other embodiments obtained by those skilled in the art without making innovative effort and on the basis of the embodiments of the present invention shall be encompassed by the present invention.

FIG. 1 is a functional block diagram of a wearable device in a preferred embodiment of the present invention. Please refer to FIG. 1, the wearable device 10 of the present embodiment comprises a micro control chip 11, a card reading chip 12 and a chip 13, the micro control chip 11 and the chip 13 are connected to the card reading chip 12, which are, specifically and preferably, electrically connected so as to realize communications therebetween. In the present embodiment:

At the recharging stage of data interaction, the card reading chip 12 is used to carry out a first data write operation on the payment account possessed by the chip 13 as controlled by the micro control chip 11, such that the payment account has the recharging data to be recharged. At the interaction stage of data interaction, the chip 13 is used to deduct the interaction data to be interacted from the payment account.

Wherein, the deduction of interaction data specifically supports two modes, one is similar to the mobile payment by swiping a card in today's life, i.e. the wearable device 10 approaches a swipe card reader and performs a data write operation on the payment account of the chip 13 via NFC (Near Field Communication), so as to deduct the interaction data from the payment account; two is online payment, i.e. the card reading chip 12 carries out a data write operation on the payment account of the chip 13 as controlled by the micro control chip 11 so as to deduct the interaction data from the payment account.

The primary object of the present embodiment is to perform a data write operation on the payment account possessed by the chip 13 of an existing e-card via the card reading chip 12 of the wearable device 10, connect the payment account, such as an offline wallet, with the online payment, use the wearable device 10 to replace the conventional swipe card reader in recharging and interaction, realize mobile payment directly with the wearable device 10, and greatly improve the convenience of an e-card solution through the portability of the wearable device 10.

FIG. 2 illustrates the structure of an application scenario of the wearable device 10 shown in FIG. 1. Please refer to both FIG. 1 and FIG. 2, the wearable device 10 further comprises an antenna 14 connected to the chip 13.

When the interaction stage is mobile payment by swiping a card, the antenna 14 in the present embodiment is used to establish connection with a first terminal when the wearable device 10 approaches the first terminal, such as a swipe card reader, such that the first terminal carries out a second data write operation on the payment account of the chip 13 unilaterally with the energy supplied by the antenna 14 so as to deduct the interaction data from the payment account.

In the wearable device 10 shown in FIG. 2, the ISO14443 protocol is preferably selected for communication connection between the micro control chip 11 and the card reading chip 12 and between the card reading chip 12 and the chip 13, and a protocol similar to USART (Universal Synchronous/Asynchronous Receiver/Transmitter) is employed in the part of transport layer protocol, comprising a synchronous clock of mobile payment and a pin, wherein the pin is used for the output TX and reception RX of communicated and transmitted data, namely achieving the pin multiplexing.

The micro control chip 11 is an MCU (Micro Control Unit) chip, preferably an STM32 chip, which is mainly used to control the card reading chip 12 to implement data read/write operations, as well as to configure the wearable device 10 to an intelligent mode.

The card reading chip 12 is preferably sized to be 4*4 mm, and has a power consumption below micro-amp when not used, leading to a relatively low power consumption. In addition, the card reading chip 12 integrates the ISO7816 protocol in the encryption and message parts, and an SPI (Serial Peripheral Interface) or I2c (Inter-Integrated Circuit) interface may certainly be selected, so as to integrate a contactless card or a contact card reader. The card reading chip 12 in the present embodiment may very well satisfy more strict requirements by some finance-related payment scenarios, and can overcome the difficulties in design of implementation of the entire protocol and highly intensive encryption through the micro control chip 11 only, as well as the drawbacks that hardware decoding is needed to meet many industrial standards.

The chip 13 is encapsulated onto the circuit board of the wearable device 10, which supports dual interfaces so as to simultaneously support the ISO14443 protocol for contactless cards and the ISO7816 protocol for contact cards. In other words, when a card reader is used for mobile payment by swiping a card, the antenna 14 supplies energy to revise the data of the payment account possessed by the chip 13; during recharging and online payment, the micro control chip 11 controls the card reading chip 12 to directly revise the data via the ISO7816 protocol.

The antenna 11 is mainly to ensure that the wearable device 10 can be compatible with card readers commonly used in today's life. In addition, the chip 13 is preferably placed within the entire wearable device 10, such that the area of the antenna 11 is as large as possible so as to ensure the practicability of card swiping.

Please refer to FIG. 1 again, the wearable device 10 of the present embodiment comprises a communications module 15, a display screen 16 and a vibration motor 17. The specific principle and process of mobile payment achieved by the wearable device 10 will be described in detail below with reference to FIG. 1:

If the data possessed by the payment account is greater than or equal to the interaction data, the micro control chip 11 further determines whether the interaction confirmation option displayed by the display screen 16 is turned on. If it is turned on, the micro control chip 11 controls the display screen 16 to display the interaction data, and controls the vibration motor 17 to vibrate to prompt the user for confirmation, thereby facilitating a prompt transaction.

If it is not turned on, the micro control chip 11 controls the card reading chip 12 to deduct the interaction data directly from the payment account, and controls the display screen 16 and the vibration motor 17 to prompt that the current interaction is completed.

After the current interaction, similarly, the micro control chip 11 will further control the communications module 15 to transmit the current interaction information back to the second terminal 22 for unified management.

Through the above description, the user may perform transaction confirmation in real time on the interaction content and interaction amount via the second terminal 22 or the wearable device 10, perform inquiries and management on historical interaction records, and in addition, update the account information of the online account.
